A Rod is a one-handed Implement that is between 24 and 42 inches long.
A Rod must be either a mace, club, or blunt instrument other than a hammer or flail. Magical markings or runes are especially fitting as decoration, but not necessary.
Any character with either of the Arcanist or Mystic Abilities can wield a Rod.
You must have one of the Abjurer or Armsmaster Abilities to wield a Rod in one hand and another Weapon or Implement in your other hand.
You can cast Spells through a Rod while you are wielding it, either when attacking a target or empowering an ally.
You cannot use Techniques such as Cleaving Blow with a Rod unless it is enchanted to let you do so.
